Pool Pumps

A pool pump is crucial to the operation of a pool. Otherwise known as centrifugal pumps they move the water around the system. The impeller in the pool pumps spins causing water to shoot out of it. As this water escapes, a vacuum is created that demands more water to match this force. Water is therefore pulled from the pool or spa and then moved on into the rest of the system. They are sized in either horsepower (hp) or kilowatts (kw), and usually have 1.5 or 2 inch unions attached to the suction/inlet (side) and the return/outlet (top) points on the pump.

Initially water is pumped from the pool, which comes via the skimmer and the main drain (sump) at the bottom of the pool. It then circulates through the pool pump with any debris not already caught in the skimmer being trapped by the basket housed inside the pump. This water is then shifted into the swimming pool filter and then depending on the position of the multiport valve it will either pump the water to your drainage area or alternatively filter it and move it into your pool heater if applicable. The pool water is then pumped through an automatic chemical dosing system if present. Following this the water is pumped back via the pool and the process is repeated. This process should usually be carried out for around 4-8 hours per day on a domestic pool when in use.
